sciencehabit writes: Researchers have developed a program, called DarwinTunes, that produces 8-second sequences of randomly generated sounds, or loops, from a database of digital "genes." Now, with input from 7000 internet users who act as "natural selectors", the program has "evolved" these bits of noise into real music. Although the resulting strains are hardly Don Giovanni, the finding shows how users' tastes exert their own kind of natural selection on popular music, nudging tunes to evolve out of cacophony.
